The stockmonkey distribution is supposed to contain all the technical analysis
tools you'd ever want. It has a few things, but it's sadly lacking.
Here's the tiny catalog so far:
Math::Business::SMA Simple Moving Average
Math::Business::EMA Exponential Moving Average
Math::Business::WMA Weighted Moving Average
Math::Business::HMA Hull Moving Average
Math::Business::LaguerreFilter Laguerre Filter (DSP technique)
Math::Business::MACD Moving Average Convergence/Divergence
Math::Business::RSI Relative Strength Index
Math::Business::BollingerBands Bollinger Bands
Math::Business::ATR Average True Value
Math::Business::DMI Directional Movement Index (aka ADX)
Math::Business::ParabolicSAR Parabolic Stop and Reversal
If you'd like to help, or even just *suggest* a module, just let me know.
Links to the algorithm are helpful as our spreadsheets with example
calculations, but they are not necessary.
I do check rt.cpan.org, so that's definitely one way to go.
